Patent CA-2195301-A1 (CA)
Title: Device with at least one hydraulic axis
Inventor: TRUNINGER ROLF
IPC: B29C45/50
Filed: 1996-05-17
Abstract: The new invention proposes control of the power of hydraulic axes on the electrical side, using the power electronics, and no longer on the hydraulic side. This makes it possible to operate the hydraulics as an open circuit system, and, in particular to use one signal pump to drive and number of axes sequentially. The main advantage is that, on one hand, the feedback control quality of purely electro-motorically driven axes can be achieved, and, above all, that the energy loss sustained in the previous mode no longer arises. One particular advantageous effect of the new drive is produced when it interacts with a potential energy source which defines the return force acting on the drive. A particularly preferred form is a gear pump with internal gears. Although the system as a whole is a four quadrant drive system, it operates as a two quadrant drive system on the pump drive side. The new invention has made it possible to apply the known "control philosophy"  used in electrical engineering, and in particular the control of power and feedback control of power, to hydraulic power systems.

Title: Licence plate screening device
Inventor: JACOBS TIMOTHY MURRAY
IPC: B60R13/10
Filed: 1997-01-24
Abstract: The device described hereafter is designed for the intent of allowing the owner/operator of a motorized vehicle to prevent the display of the vehicle's licence plate numbers/letters. By means of combining a licence plate cover and a fresnel lens the licence plate cover can appear transparent or translucent depending on the observer's angle of view. The licence plate cover will be made of a transparent plastic compound with a lens, also made of a transparent plastic compound, attached to the inside surface. It is the intent of this patent to register Tim Jacobs as the inventor of the licence plate cover which incorporates the use of a fresnel lens inside the licence plate cover which causes translucence when viewed from a predetermined angle. It is the combined use of a licence plate cover incorporated with a specifically designed fresnel lens which makes this new product unique and therefore warranting patent protection. The lens when viewed from a specific angle (and beyond) 'bends' the light causing opacity or translucence to occur in a portion of the lens while the rest remains transparent. (A fresnel lens consists of a series of angled concentric circles moulded into a transparent plastic compound. It is used primarily for purposes of magnification). Alteration to the fresnel lens size or magnification, its distance from the licence plate and the type or size of licence plate cover can alter the amount and angle of initiation of translucence and should be considered obvious to the original inventor.

Title: A method and a system for manufacturing broad airlaid paper webs containing an absorbing powder
Inventor: MOSGAARD CHRISTENSEN JOHN HARL
IPC: A61F13/15
Filed: 1995-09-06
Abstract: In the production of airlaid paper webs it is possible to add super absorbing powder materials, typically by addition either beforehand, to the fibre material to be distributed, or subsequently, viz. to the top side of an already formed web, between successively formed layers thereof. Both methods involve drawbacks, and with the invention is has been recognized that it is advantageous to introduce the powder material at an intermediate stage between the initial supply of the fibres to the airlaying unit and the final formation of the web; thus, a first coarse distribution of the powder is effected in a compulsory manner, independently of the initial supply of the fibre material, while the final distribution of the powder is effected by means of the same air flows which cause the final distribution of the fibre material for forming the even web layer. In this manner the powder is effectively mixed evenly into the fibre material.

Title: Modulating the immune response
Inventor: DEMPSEY PAUL WALTER
IPC: A61K47/48
Filed: 1995-12-06
Abstract: Coupling of C3d molecules or ligands of CD21 or CD19 to an antigen alters the level of immune response to the immunogen upon its administration to an individual. For C3d, the magnitude of the effect is dependent on the number of C3d molecules included in the conjugate. Conveniently, C3d molecules or CD21/CD19 ligands are coupled to an immunogen in fusion polypeptides which may be produced by expression from encoding nucleic acid, for instance by culturing host cells containing the nucleic acid. Other means of associating the molecules include chemical cross-linking and co-expression on the surface of a carrier structure. Administration of compositions comprising, in a preferred embodiment, C3d molecules and an immunogen of interest may be used prophylactically (by virtue of the immunological memory induced) or therapeutically. The administration may be for the purpose of raising antibodies to the immunogen. A T-cell response may also be induced.
